LASIK (Laser In-Situ Keratomileusis) for Nearsightedness

LASIK (laser in-situ keratomileusis) is a surgery that flattens the cornea . It is the most common laser surgery for correcting nearsightedness (myopia) and astigmatism. LASIK makes a small flap in the cornea and removes some of the tissue exposed by the flap. The laser removes tissue from the cornea very accurately…

Neovascular Glaucoma

Glaucoma is a group of eye disorders that damage the nerve at the back of the eye (optic nerve), resulting in loss of eyesight, especially peripheral (side) vision. Neovascular glaucoma is a type of severe glaucoma in which blood vessels in the iris block the normal drainage of fluid out of the eye, causing increased…

Laser In-Situ Keratomileusis (LASIK) for Farsightedness

Laser in-situ keratomileusis (LASIK) is the preferred procedure for correcting farsightedness (hyperopia). It changes the shape of the eye. In LASIK, a thin flap is made on the cornea using a blade or laser. The flap is lifted, and a laser is applied to the central corneal tissue. The laser makes contact with the cornea…

Tonometry

A tonometry test measures the pressure inside your eye, which is called intraocular pressure (IOP). This test is used to check for glaucoma, an eye disease that can cause blindness by damaging the nerve in the back of the eye ( optic nerve ). Damage to the optic nerve may be caused by a buildup of fluid that does not…
